8000 rpm angle grinder RP-GA7020

Safty Instruction

A recoil is a sudden reaction to a squeezed or stuck spinning wheel, back pad, brush, or any other accessory. Squeezing or hooking causes a rapid stall of the rotating attachment, which in turn causes the uncontrolled power tool to be forced in the opposite direction to the rotation of the attachment at the restraint point. For the previous ample, if the grinding wheel is snagged or pinched by the workpiece, the edge of the grinding wheel entering the pinch point may penetrate deep into the surface of the material, causing the grinding wheel to crawl out or kick out. The wheel can jump towards or away from the operator, depending on the direction the wheel is moving at the squeeze point. Under these conditions, the grinding wheel may also break. Kickbacks are the result of misuse of power tools and/or incorrect operating procedures or conditions and can be avoided by taking the appropriate precautions given below.
a) Firmly hold the power tool and adjust the position of the body and arms to resist the recoil force. Always use an auxiliary handle (if provided) to maximize recoil or torque reaction during start-up. If proper precautions are taken, the operator can control the torque reaction force or recoil force.
b) Do not put your hands near rotating accessories. Accessories may bounce off your hand.
c) If recoil occurs, do not place your body in an area where the power tool will move. The recoil will push the tool in the opposite direction to the wheel movement at the hook point.
d) Be especially careful when handling corners, sharp edges, etc. Avoid bouncing and snagging attachments. Corners, sharp edges, or bounces can easily snag rotating accessories and cause loss of control or recoil.
e) Do not install chainsaw woodcarving blades or serrated saw blades. This blade can cause frequent recoil and loss of control.
